THREAD-CUTTING TEMPLE FOR LOOMS.

Application filed March 20, 1926. Serial No. 96,174).

This invention relates to a thread cutting temple such as is employed particularly in connection with the automatic filling replenishing loom and which acts to sever close to the selvage any filling ends left extending therefrom.

The object of the invention is to provide such a device in which the cooperating cutter members are mounted in fixed position or in other words v so mounted as to effect their relative opening and closing movements without having any bodily movement.

The object of the invention is further to provide such a device in which one of the cooperating cutter elements is rigidly held in fixed position and the other element is pivotally mounted to open and close with respect to the fixed element and consequently without bodily movement in the temple head.

The object of the invention is further to provide such a device in which the movement of the movable cutting element is secured by an actuator lever, which is held against bodily movement by being pivoted in the temple head.

The object of the invention is thus further to provide such a device in which all the parts are accurately and permanently positioned in the temple and in which the movements necessary to effect the cutting action are secured without bodily movement.

The object of the invention is further to provide such a device in which the fixed cutting element straddles the movable cutting element and bears thereagainst at both sides so asto present two lines of shearing cut and thus further assure the severance of the filling when the cutting movement takes place.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

1 is a view in side elevation of a temple embodying a preferred form of the invention wi h the parts shown in the position assumed when the cutter members are in open position.

Fig. 2 is a view similar to Fig. l with the parts in the position assumed when the cut ter members are in closed position.

Fig. 3 is a view in front elevation of the temple.

Fig. l is a detail in vertical cross section taken on the line 44 of Fig. 3.

As the general construction and operation of the thread cutting temple is well known and familiar to those skilled in the weaving art, it is only necessary here to illustrate and describe such device sufiiciently to disclose the present invention.

The temple stand 1 is usually a hollow box-like structure secured in place to the breast beam of the loom. lhe temple comprises a head portion 2 with a shank 3 extending forwardly therefrom. This shank is mounted to slide longitudinally in the temple stand 1 and is normally held projected rearwardly by the usual spring 4 within the stand and surrounding the shank. The temple head contains the usual pin roll 5 journalled on a stud or studs 6 mounted in the head. The temple head is also provided with the usual depending heel 7 which is struck at each beat-up of the lay to force the temple head with its shank slightly forward. As the lay retracts, the spring i slides the shank and temple head back to their rearward position.

The cutting instrumentalities are usually mounted in a slot such as the slot 8 extending vertically through the temple head adjacent the end of the pin roll.

The cutting instrumentalities in this invention comprise a pair of relatively movable shear cutting elements in which the upper element is mounted in fixed position and the lower element is movable toward and from the upper element and preferably in the form of a cutter member pivotally mounted in the temple head. Both the elements are thus fixed against bodily movement. in the construction illustrated as the preferred form of the invention, the lower cutting element is in the form of a blade 9 mounted in the slot 8 and pivoted on a stud 1O rigidly secured in the temple head. At its rearward end this blade is hook-shaped presenting a concave upwardly facing surface havin at each side cutting edges 11.

' At its forward end this blade is provided with a longitudinal slot 12. The upper cutting element is in the form of two fixed blades, one extending at each side of the blade 11 and therefore the upper element as a whole straddles the lower element. These fixed blades are in the form of metal plates 13 mounted in slots at the top of the temple head and held in place by a set screw 1%. These blades are bent toward each other as shown in Fig. 3 and are somewhat springy so that they tend to press against the blade 9 at each side thereof. The cutting edges of the blades 13 are formed on the downwardly and rearwardly projecting portion 15 of each blade.

An actuating lever 16 is pivotally mounted on a stud 17 on the temple head. At its lower end this lever 16 is formed to present a depending heel 18 and at its upper end is provided with a stud 19 which fits in the slot 12 of the movable cutter blade 9. A spring 20 is wound about the stud 17 and at its upper end is caught or locked against the stud 21 on the temple and at its lower end is formed into an eye 22 engaging a stud 23 extending transversely from the heel 18. This spring therefore tends to move the actuator lever 16 at its pivot counter-clock wise and to hold it normally in the position shown in Fig. 1. When the lay in beating up strikes the heel 18, it swings the actuating lever 16 clockwise carrying it into the position shown in Fig. 2. The stud 19 and slot 12 are so designed that as the actuator lever 16 is moved back and forth between the position shown in Fig. 1 and Fig. 2, it swings the movable cutter blade 9 on its pivot 10 from open to closed position and vice versa, or between the positions shown in Fig. 1 and Fig. 2. In normal position the cutter members stand as shown in Fig. 1, leaving between them an opening through which the filling end is carried. As the cutter blade 9 swings to closing position the filling end guided in the notch 24 in the temple head extends between the blades and is caught and held thereby before the severing act-ion takes place. As the movement of the blade 9 continucs, the movable blade, being pressed at each side by the two fixed blades 13, has its cutting edges 11 carried against the co-opcrating cutting edges of the projection 15. Consequently the filling is severed at one or two points, and usi'ially at two points, by the cooperating cutting edges, thus assuring a clean and accurate cut.

The movable cutting blade 9 is so shaped as not to interfere with the pin roll stud 6 and so as to allow as wide an opening or downward movement as possible. i

A very simple construction is thus provided in which all the parts are permanently and accurately held in position in the temple head and in which an accurate and certain cooperation of the cutting elements is always secured.

i'L rubbing action between the cutting portion of the movable blade 9 and the projections 15 of the fixedblades 13 maintains the cutting edges sharp and at any time the blades 13 may usually be removed and replaced by removing and replacing the screw 14-, thus enabling them to be resharpened if desired.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:

1. A thread cutting temple for a loom comprising a head, a cutting element rigidly mounted in said head and provided with a projection having a downwardly and rearwardly inclined cutting edge, a cooperating movable cutter blade held against bodily movement in the head, and provided with a hook-shaped end projecting rearwardly beyond the temple head and having a concave cutting edge cooperating with the cutting edge of the said projection, and an actuator lever pivotally mounted on the temple, connected to said movable blade, and acting when moved in one direction to efi ect the cutting movement and when moved in the opposite direction to efiect the opening movement of the movable blade.

2. A thread cutting temple for a loom comprising a head, a pair of cutting blades rigidly mounted in said head and presenting projections rearwardly beyond the temple head each provided with cutting edges, a cutter blade pivotally mounted in the temple head to move between and bear against the said rigidly mounted cutting blades without bodily movement and presenting cutting cages to cooperate with the edges respectiveof said rigidly mounted blades, and an actuator lever pivotally mounted on the temple, connected to said movable blade and acting when moved in one direction to effect the closing movement of said blade and when moved in the opposite direction to effect the opening movement or" said blade.

A thread cutting temple for looms comprising a head, a cutting element mounted in said head, a co-operating pivotally movahle cutting blade held against bodily movement in said head, a swinging actuator mounted in said temple having a heel projecting into the path of the lay and a pin and slot connection between said actuator and said pivotally mounted blade operable by the sliding movement of the pin in the slot when the actuator is moved in one direction to effect the cutting movement and when moved in the opposite direction to effect the opening movement of the pivotally mounted blade.

1. A thread cutting temple for looms comprising a head, an upper cutting element having a pair of resilient cutting blades presenting projections rearwardly beyond the temple head each provided With cutting edges, acutter blade pivotally mounted in the temple head to move between and engaged by the resilient cutting blades and presenting cutting edges to co-operate with the edges respectively thereof, a swinging actuator connected to the movable blade and operable when moved in one direction to effeet a closing movement of said cutting blades and when moved in the opposite direction to effect the opening movement of said cutting blades.

In testimony whereof, I have signed my name to this specification.
